Answer:
Because they are hydrophilic
Explanation:
The cell membrane is made up of a phospholipid bilayer. The phospholipid bilayer is made up of an arrangement of phosphate heads, which are (attracted to water) hydrophilic, and fatty acid tails, which are hydrophobic. (repelled by water).
Because they are attracted to water, the phosphate heads face the outside of the cell, where the water is
Is there anything else that needs to be added to this in order for me to answer this question??
In plant cells we can see cell wall and also plant cell organelles are membrane bounded beacuse they are eukaryotics .
so answer is plants.
Answer: topoisomerases
Explanation:
Topoisomerases are enzymes that help overwind or underwind DNA. DNA double helix has high tedency to get winded again because of its structural characeristics.
During replication and transcription of DNA, DNA gets overwound in front of a replication fork. This enzyme stops the double helix of DNA from becoming too tightly bound in front of the replication fork as the DNA opens.
The given demonstartion shows the action of topoisomerases as it shows unwinding of of supercoiled strands of pipe (DNA), which is don eby topoisomerases in the DNA replication process.
Hence, the correct answer is topoisomerases.
TGCATGG because A pairs with T ( I remember with apples in the tree) and C pairs with G ( I remember this one with cars in the garage)
